INITED PATTERN MECHANISM FOR EMBROlDERlNG-MACHINES.

SPECIFICATION forming part of Letters Patent N 0. 714,817, dated December 2,

Application filed April 9, 1902.

To all whom it may concern.- Be it known that 1, DAVID NADEL, a subject of the Emperor ofGermany, residing at Spindism for Embroidering-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to embroidering-machines, especially machines of the Bonnaz type, illustrated in United States Patent No. 83,910. It is more especially an addition to the invention disclosed in my patents of April 8, 1902, Nos. 697,269 and 697,270. Its object is to provide an attachment by which the automatic feed-control mechanism may at the will of the operator be put out of action and a hand-operated means substituted; and to this end it comprises, essentially, an adj ustable device, such as a dumb-bell pinion, interposed between the hand mechanism and the power or automatic mechanism to receive and transmit the power from either.

In the accompanying drawings, Figure 1 is a bottom plan view of the essential elements andimmediatelyadjunctivemechanism. Fig. 2 is a side; elevation looking in the direction of the arrows of Fig. 1. Fig; 3 is a section on the dotted line of Fig. 2 and lookingin the direction of the arrows of that figure; and Fig. 4 isa section on the dotted line of Fig. 3 looking in the direction of the arrows.

1 represents a driving-pulley 2 and 3, driving-gears; 4, a shaft, and 5 a bracket in which the shaft is mounted. These are allfamiliar features in this class of machines. So, also, the looper-c'ontrolling mechanism, comprising the bracket 6, the lever-arm 7, the rod 8, the worm 9, and the guide-bracket 10, is afamiliar feature, being particularly shown and described in the cited patent to Bonnaz, N0.

83,910, andbeing illustrated here in a merely incidental manner to assist in locating the other parts. The pattern-drum 11, with its Serial No. 102,0 l7. (No model.)

control the feed mechanism, the crank-arms imparting the power through the shaft 18 and gear-wheel 19 to the shaft 20 through an intermediate mechanism, a gear device, to be hereinafter described, the shaft 20 in turn through a gear-wheel 21 meshing with a gearwheel 22, rotating a shaft 23, and through gears 24 and 25 in turn rotatinga shaft which imparts the requisite power. to mechanism fully illustrated anddescribed in my preceding cited patents to control the feed mechanism, not necessary to illustrate here, it being sufficient to say that the ultimate purpose is to control the action of the shaft which bears the gear-wheel 25.

In the earlier artas, for example, in the cited Bonnaz patent-it was customary to employ a hand mechanism for controlling the feed mechanism. Even with the automatic regulation, such as given by the mechanism of my preceding cited patents, it is sometimes desirable to employ the hand mechanismas, for instance, where it is desired to place some intricate pattern at a corner. To this end I have joined with the automatic mechanismthat is, the pattern-drum, with its complementary paths-the connection rods, the crank-arms at an angle to each other, and the power-transmitting mechanism, as described, the familiar hand mechanism comprising a crank-handle 26, a bracket 27, and a shaft 28, bearing a gear-wheel 29. i The essence of my invention lies in the joining of the automatic controlling devices with the hand devices and interposing a mechanism by which the power may at the will of the operator pass: either through the automatic mechanism or the hand mechanism to the shaft borne by the gearwheel 25. In the illustration the intermediate mechanism is a double or dumb-bell pinion 30, which plays upon a feather on the shaft 20, and a shifting-lever 31, pivoted to the frame or bed'of the. machine at 32 and having a locking-screw, to be usedwhen desired, at*33.

34 on the end of a shaft 35, which is journaled in a bracket 36, and bears at the other end a gear-wheel 37. The gear-wheels of the dumb-bell pinion may mesh in turn with the gear-wheel 19 on one side or the gear-wheel 37 on the other side. When the machine is running in the usual manner, with the pat- The gear-wheel 29 meshes with a gear-wheel,

tern-drum, connection-rods, and crank-arms governing the feed mechanism, the shifting-1ever may be locked. The gear-Wheel 19 then engages the outer gear-wheel of the dumb-bell pinion 30 and through the shaft 20 and the succeeding connection drives the shaft which carries the gear-wheel 25'. When it is desired to use the hand mechanism at difficult turns or at will, the shifting-lever 31 is brought into use and the dumb-bell pinion is shifted on the shaft 20, so that power applied by the operator to the handle 26 may, through the shaft 28, gear-Whee134, shaft 35, and gearwheel 37, drive the shaft 20 through the inner gear-Wheel of the dumb-bell pinion 30.

Having fully described my invention, what I claim is-- 1. A feed-controlling mechanism for embroidering and other machines comprising an automatic mechanism for controlling the feed, an independent hand mechanism for performing the same function, and an intermediate adjustable mechanism which may at the will of the operator be moved into engagement either with the automatic mechanism or with the hand mechanism to receive and transmit the power from either of the governing mechanlsms.

2. A feed-controlling mechanism for embroidering and other machines comprising an automatic power mechanism including a shaft bearing a gear-wheel, a hand-power mechanism including a shaft bearing a gear-wheel, a

shaft bearing a dumb-bell pinion adj ustabler thereon, and means for shifting the dumbbell pinion into engagement with either the gear-Wheel of the automatic mechanism or the gear-Wheel of the hand mechanism.

In testimony whereof I affix my signature in presence of two witnesses.

D. NADEL.
